Hello, my XiPKI version is 6.5.3. When I use my CMP client device to communicate with XiPKI, which will act as the CMP server for certificate enrollment，but it seems XiPKI returns no response.

I conducted the following troubleshooting steps:

1. I executed the cmp-client.script, and it ran successfully.
2. I used tcpdump to capture network packets and confirmed that requests from my CMP client device were sent to the server.
3. The URL I used is http://:8082/gw/cmp/. Port 8082 matches the gateway.http.port configured in /xipki-software/setup/conf.json and the HTTP port defined in server.xml for tomcat-xipki-gateway.
4. My CMP client can successfully request certificates from EJBCA, which proves that the CMP Initialization Request (IR) messages I send are correctly formatted and valid. This indicates that the issue likely lies in the server-side configuration or communication setup with XiPKI.

I am unsure why this issue persists. Could you help me resolve it?
